Overview
Arai's attempt to court his savior, the bar manager Okabe, is relentless. It all began the day when Okabe saved him from a tangle with a hoodlum. Despite his flirty reputation, Arai was in fact an absolute beginner in love. Okabe kept refusing his advances until he finally suggested a one-night stand with the university student. A sensual, yet lovely story between a frivolous-looking student who's seriously in love, and a well-built, older bartender!
